Answer:
Step-by-step explanation:
1) Find the mean of the following numbers: 5, 11, 8, 8, 7, 4, 10, 9, 7, 7, 6
SashulF [63]
Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, mean = 73/10
Mean = 7.3
The equation describing the situation is given by
y - 0 = (5 - 0)/(47.5 - 0) (x - 0)
y = 5/47.5 x
y = 2/19 x
Therefore, it will require 19(11)/2 = 104.5 minutes to jog 11 miles.
1. x=1
5x=4+x
4x=4
x=1
2. x=3/4 or 0.75
2/3x=1/2
2x=1 1/2
x=3/4
3. x=1
3x-2x+4=15/3
x+4=15/3
x=1
4. x=5
4x+7=2x+17
2x+7=17
2x=10
x=5
5. x=20
.5x=10
x=20
